Abstract (en)

[origin: EP1814134A2] A power supply apparatus (60) for supplying predetermined supply voltages respectively to an anode electrode (40), a cathode electrode (11), a collector electrode (30), and a helix (20) of an electron tube. The power supply apparatus comprises an anode switch (65) for turning on/off the anode voltage output, and an anode switch control circuit (66) for controlling the on/off operation of the anode switch such that a pulsed anode voltage is repeatedly applied to the anode electrode a plurality of times at a predetermined period when operation of a helix power supply (61) and a collector power supply (62) is stopped.
